1 General Description
This specification provides general information regarding performance and integration of W2SW0011, a
complete wireless subsystem featuring 802.11 b/g/n WLAN capabilities in a small form factor module.
The W2SW0011 device is designed to simplify the process of adding wireless capability without lengthy
design cycles or complex RF design. It is completely tested for functionality and performance along
with coexistence with other wireless standards. A full menu of certifications will also be provided,
simplifying the certification process for your end product while further reducing valuable time-tomarket. Based on world-class silicon from Marvell, the W2SW0011 has been fully optimized for
throughput and receive sensitivity using careful design practices. Software development resources are
available to create drivers for unique processors and operating systems if needed, and to optimize the
wireless subsystem for your application.
The specification maximum and minimum limits presented herein are those guaranteed when the unit is
integrated into the Wi2Wi’s W2SW0011-DEV Development System. These limits are to serve as
representative performance characteristics of the W2SW0011 when properly designed into a customer’s
product. Wi2Wi makes no warranty, implied or otherwise specified, with respect to design and
performance characteristics presented in this specification when used in customer designs.
This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation. Changes or
modifications not expressly approved by the party responsible for compliance could void the user’s
authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses, and can radiate
radio frequency energy and, if not installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
Consult the dealer or an experienced radio/TV technician for help.
This equipment complies with the FCC RF radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with a minimum distance of 20
centimeters between the radiator and your body.
